Call User made Python modlue from Matlab

2 views (last 30 days)
I am having trouble calling a python module (wirtten by me) from matlab. I saw simarl questions and aswer but no onw I found was useful to be. Here are the details:
I have installed Python 3.8 on Windows via the official python website.
In matlab I set the path to the python executable using pyenv:
py = pyenv('Version', 'C:\Users\giaco\AppData\Local\Programs\Python\Python38\python.exe');
Since my module is in another folder I add this folder to the python search path using the function py_addpath (found on the matlab file exchange)
The path seems to be added correctly infact py_paths is:
py_paths =
7×1 cell array
{0×0 char }
{'C:\Users\giaco\Documents\PROJ_WORK_Thesis' }
{'C:\Users\giaco\AppData\Local\Programs\Python\Python38\' }
{'C:\Users\giaco\AppData\Local\Programs\Python\Python38\DLLs' }
{'C:\Users\giaco\AppData\Local\Programs\Python\Python38\lib' }
{'C:\Users\giaco\AppData\Local\Programs\Python\Python38' }
But when I run my module as:
the=py.thetae.thetae(, r.ta, r.rh);
I get the following error:
Unable to resolve the name py.thetae.thetae.
Any suggestion on how to solve this?
Thanks in advance!

Try adding adding the path as:
Please verify the following points as well
  1. A file called exists in your 'C:\Users\giaco\Documents\PROJ_WORK_Thesis\' directory.
  2. The file if exists has the function thetae defined in it.
